ELECTRICAL HEATER. y

My present invention relates to'improvements in electrical heaters designed especially air may be taken from the -floor level and passed through the heater yand then Ydistribut ed tothe several rooms in a house or other building, thus insuring a circulation of an' within the house, venting of the house, and

' aneiicient heating system for the house.

In carrying out my invention, I utilize an electric water heater and employ means for directing air ycurrents against the radiating surfaces which are heated Yby the hot water.

The heater utilizes an annular water chamber and a central interior air chamber through which the air currents are passed for the purpose of beingheated.` y

The invention consists in certain novel combinations and arrangements of parts as will hereinafter be more fully pointed out kand claimed.

In the accompanying drawings, I have illustrated one complete example of the physical embodiment or' my invention wherein the parts are combined and arranged according to the best mode I have sok far devised for the practical application of the principles of my invention.

Figure 1 is a top plan View of the electrical heater with the hot air hood and lues omitted;

Fig. 2 is a vertical sectional view ofthe heater on line 2-2 of Fig.V 1;

Fig. 3 is a top plan view showing the dome or hood and the hoodv air iues :connected thereto;

Fig. 4 is a detail sectional view 'showing one of the stay bolts between the spaced any nular walls of the heater; and

Fig. 5 is a view of one of the electric heating elements, detached.

In carrying out my invention, I utilize a double wall heater of ycylindrical shape comprising theouter wall 1 and the inner wall 2, between which is formed an annular water chamber 3. The usual stay bolts S are employed for bracing the walls of the heater, an

the annular water chamber 3 is closed at the bottom by a circular plate 2a and at the top by a circular plate 2b. The heater is encased within or enclosed by an insulating wall 4 fashioned of suitable material to prevent excessive radiation of heat which is generated in the water in the chamber 3.

The heater is elevated from the ground or floor a suitable distance to permit circulation of air thereunder, and is supported upon legs 5 to permit the air currents to pass under the heaterand up through the central internal air chamber 6. This chamber is opened at the bottom, but at its upper end, a. screen 7 is arranged, and a dome 8 having a iiange 9 is boltedto the circular plate 2", to close the upper end ofthe central air chamber. The currents of hot air passingy into the dome 8 enter the hot air lues 11, andthe heated air is conveyed to the desired destination'as the separate rooms of a dwelling. y

To enlarge the radiated surfaces within the heater, in addition to the interior surface oi' the inner cylinder 2, I provide transversely extending water tubes 12 which extend diametrically of the interior air chamber, and afford communication `at opposite points between the annular water chamber. In this manner, the water is permitted to circulate and the exterior facesof the water tubes provide heat radiating surfaces against which the air in the central internal air chamber contacts, and the air of course is heated by this contact.

The electrical elements for heating the water in the water chamber are indicated as 13, and a suitable number of these elements may be employed. The elements are submerged in the water in the water chamber and their wires 141 are passed through openings 15 in the top plate 2b and thence through insulated caps 16 which are secured by bolts 17 to the top plate 2. In order to increase the circulation of air currents, I provide an electric motor 18 in the lower end of the air chamber which is supported upon a bracket 19 and this motor has a tan or impeller 20. It will be apparent that the impeller will be instrumental in causing an upward flow of air cur rents from the floor level through the interior air chamber where the air currents are heated, and thence through the hot air lues. A

be operated bytheV motor 18 to Cause circulation of air, and'itwiil be apparent that'tlie` cool air is drawn in under the heater'and passed up through the air yeharnberand means ot the airfflues Ythe cool .air is distributed to the variousparts of a House.

rl`hus the device may be located in an artifi- `eially cooled chamber and the impeller 2OV Yused to distribute the 'Cooledy air currents v through the air tlues l1, thus CreatingaA circulation 'of a-ir through afhouse (and uniform ly Cooling the 'entire house Witht'he ar'tiiieial- Y ly refrigerated air Currents.

Having thus fully deseribed my invention, what 'claim as new-and desire to see-ure by Letters Patent is- V y il. The Combination` with a heater Comprising spaced vdouble Walls to -form an annular Water' chambery of heating` elements in said Water 'Clia'r'nbeigy a dome closing the top of the central air Chamber formed Within the inner Wall, het air fines-'connected to said dem@ and means for causingV circulation of air'witliin thej'air chamber whereby radiated heat is conveyed to thejhot air lu'es.y Y

2. Y The'combination yin a heater comprising *Y a 'pair of double Walls forming a Water chamber, of diametrica'lly arranged Water Y tubes extending across the air chamber Within the inner Wall, means for heating the. Water Withof the air eliamberyand hot air iiues conne'utedA of spaced Walls forming anl annular WaterVV ehainberand an interior air chambery-and Water tubes in said an chamber Connected With the Water chamber, of an `electric heating element in the' Water chamber,V a motor and impeller for air currents at the lower end of the air chamber, a dome atthe upper endet the air chamber, and hot air'ues connected tol said dome.

In testimony whereof v IS affix my signature.
